All of the prolotherapy dextrose injections will be performed under ultrasound guidance. Prolotherapy patients will receive 5 sessions approximately 4 weeks apart. In each session, 6 injections in different areas of the lumbosacral spine, and sacroiliac ligaments will be injected with 20% dextrose solution using a 25 gauge needle. The targeted structures include the following: the facet joint capsular ligaments, interspinous ligaments, and some of the sacroiliac ligaments, all depending on the clinical assessment. The clinical picture will determine what levels will be injected in each session.
